Female sitting base

Boosh, been a while since I did a base. It was simple enough to do. Original image is from High school of the dead, Saeko. Credit back to me if you use it so I can see . Also it is a PNG file so I hope that helps? Im not sure what to save it as. Everyone tells me something different but Ive been told PNG is better. If not let me know and Ill try uploading as something else >_>.
